#3.5 xx10^-8#


Scientific notation is a way of writing very big or very small numbers quickly easily and accurately and avoids having to write all the zeros as place holders.

The format is a number between 1 and 10 followed by a power of 10. If the number is big, the power will be positive, if the number is a small decimal, the power of 10 will be negative.

Move the decimal comma from its position until it is to the right of the first digit of the number. The number of places you move the point will be the power of 10.
